[RASMB] interference optics

[Ute Curth]

Dear all,

I hope you had a good start in 2013 and some of you can possibly give me 
advice on a problem with our Xl-I machine.The raw data of  our 
interference optics show (and always showed) such an enormous vertical 
jitter that it is hard to judge whether the sample sediments at all and 
where the meniscus is located (see attached file). Whereas, after 
subtraction of TI and RI noise the data look quite nice, I am wondering 
what the reason of this jitter is. Has anyone an idea about its possible 
source and how I can get rid of it?

Thank you in advance

Ute
